November 25, 200915 yr All I can think of suggesting is if you cut the exhaust yourself, make sure you mark across any welds you intend to grind away( @ 90 degrees to the weld) as to give the welder something to line up-to when its welded back together. Personally I wouldn't attempt it without a spare/backup front pipe in-case things go wrong. As for not removing the CAT why not?, mine has been off for 1000 miles or so with a complete big-one exhaust system, went through an MOT like this as they don't test emissions on bikes where I had my test done. Its only there to comply with EU legislation. Vez...
November 25, 200915 yr Moderator Hi, my DEP silencer will be arriving soon (hopefully tomorrow) so I'm looking for a few tips. I've read the guide on dtr125.net and I know I'll have to cut the exhaust in 2 and remove the washers welded on it inside (I won't be removing the CAT ) but I'm worried that the exhaust won't be welded back together properly so it won't fit properly... any tips to avoid this? I think I will be cutting the exhaust myself then handing it over to a professional welder... not sure yet. The cost of getting it welded professionally unless its your Dad/Brother/Sister/Friend will be more than a new pipe so fit the proper performance part and keep the original for when you sell it.
